Here is a breakdown of some of the methods that your leak detection surveyor may employ:
Thermal imaging cameras are used by specialist surveyors to detect and investigate hot and cold pipework hidden within hard surfaces and can identify pipework leaks, e.g. a burst pipe. Thermal imaging cameras can inspect large areas quickly as well as eliminate the need for more destructive, invasive methods of leak detection.
Correlation and Acoustic Detection
Surveyors use specialist equipment, which can identify leaks through the different sounds emitted by the escape of water, as well as any changes in vibrations. Other forms of equipment use microphones to record the noise from leaks in order to identify the location.
This employs the use of a hydrogen and nitrogen gas, which is released into the water pipe. The leak is then detected by specialist tracer equipment as it escapes the pipe at the point of the leak.
Dye tracing is a fast and effective way of identifying the flow of water, as well as identifying the position of a leak. Fluorescent dye is added to a water stream, and a UV light is then used to search for evidence of the dye in potential leak spots. Tracer dye is completely safe to use and eco-friendly.
